[EDIT: Problem solved.]
Before an update is installed, could I be asked if I would like to install it at that precise moment? Just a simple 'Yes' or 'Remind me later' function would be enough. (If the feature already exists somewhere in the preferences for Security Scan Plus, please tell me where it is).
I find that McAfee has a tendancy to annex my netbook while it is downloading and installing updates. This kills your work flow. When the fan starts humming, Videos start to drag, windows don't respond and I experienace text input lag, I know a pop up window telling that an update was installed is not far away. While I value the product, I just wish it would not make assumptions like this.
